JAC Heyue has a fuel tank capacity of 55L, which is the officially announced data. The recommended fuel grade for JAC Heyue is 92 octane, with a fuel consumption of 6.6-7.6L per 100 kilometers. A full tank can cover a distance of 723-833km. During daily driving, it is necessary to always pay attention to the remaining fuel level in the tank. Generally, the fuel level is observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are about 2 segments left to avoid running out of fuel midway. During the actual refueling process, the amount of fuel may exceed the calibrated volume. This is because the fuel tank capacity specified by the car manufacturer is measured from the bottom of the tank to the safety limit, and there is still some space from the safety limit to the tank opening. This space is designed to allow for fuel expansion when the temperature rises, preventing overflow from the tank. If the fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the calibrated tank capacity.

I've been driving the JAC Heyue for several years with a 45-liter fuel tank. Every time I fill up with 92-octane gasoline, it can run over 500 kilometers. For urban commuting, I only need to refuel once a week, which is quite hassle-free. On highways, maintaining a speed around 80 km/h reduces fuel consumption to below 6 liters per 100 km, extending the range to over 550 kilometers. For routine maintenance, it's important to check the fuel cap seal during servicing to prevent dust from affecting fuel quality, and clean the filter screen every 10,000 kilometers to avoid clogging. Over long-term use, I find the tank capacity well-designed without much wasted space, offering high safety and minimal risk of fuel leakage even on bumpy roads. As a family car, the 45-liter tank makes travel more flexible and convenient.

What Causes Fluctuating Car Engine Temperature?

Fluctuating engine temperature in a vehicle is usually caused by wiring faults or sensor abnormalities. Related fault descriptions are as follows: Introduction to wiring issues: Primarily involves grounding problems. Poor grounding, insufficient grounding points, or accidental grounding of wires can all lead to unstable engine temperature. First, check the vehicle's grounding points for firmness and signs of rust. Then inspect the instrument cluster's grounding points for looseness or corrosion. Reasons for fluctuating engine temperature: Sudden temperature fluctuations while driving may be caused by system failures, specifically sensor abnormalities. Sensor issues typically stem from quality defects or temporary malfunctions. In such cases, performing a battery reset for initialization can help determine if the fault persists.

What is the reason for the sudden disappearance of the car dashboard speed display?

The reason is the damage to the vehicle speed sensor. Here are the relevant details: 1. Vehicle Speed Sensor: As the information source for the automotive electronic control system, it is a critical component of the system and one of the core research areas in automotive electronic technology. It detects the speed of electronically controlled vehicles, and the control computer uses this input signal to manage engine idle speed, torque converter lock-up in automatic transmissions, automatic transmission shifting, the opening and closing of the engine cooling fan, cruise control, and other functions. 2. Vehicle Speed: Vehicle speed refers to the distance a car travels per unit of time, commonly referred to as speed, with common units being kilometers per hour or meters per second.

How long does it take to get a new car license plate?

If you choose a custom license plate, it usually takes about 15 days to have it made. During the registration process, you will first be issued a temporary license plate and given a receipt for picking up the permanent plate. You can then take this receipt to the vehicle management office to collect your license plate when it's ready. Try to avoid the peak period for new car registrations if possible. The normal working hours of the vehicle management office are from Monday to Friday, 9:00 AM to 5:00 PM. The busiest day of the week is Monday, while Thursday and Friday tend to be the least crowded. You can plan your visit accordingly.

What is the function of automatic transmission fluid in cars?

Automatic transmission fluid in cars serves as a lubricant to maintain system cleanliness and prolong the lifespan of transmission components. It offers resistance to low temperatures and ensures effective lubrication even in cold conditions, reducing fluid loss under harsh operating conditions. Depending on the transmission structure, transmission fluids are categorized into automatic transmission fluid (ATF) and manual transmission fluid. Approximately 95% of automatic transmission fluids are red in color. Beyond lubricating and cooling the planetary gear set, their primary role is to transmit power. Under normal driving conditions, automatic transmission fluid should typically be replaced every 120,000 kilometers, while under severe driving conditions, replacement is recommended every 60,000 kilometers.

Is Waxing Necessary After Vehicle Crystal Coating?

After applying crystal coating to a vehicle, waxing is unnecessary. The circumstances requiring waxing and methods to determine coating failure are as follows: When Waxing Is Needed: If the crystal coating fails, it's advisable to wax the car. Minor scratches are inevitable during daily use, and without proper protection, prolonged exposure can easily lead to paint damage. How to Determine Coating Failure: Hydrophobic Test: If the coating is effective, water droplets will bead up like dewdrops on a lotus leaf when splashed on the paint. If it fails, water will spread and cling to the surface. Crystal coating enhances gloss; if the paint appears dull and the surface attracts dirt easily, the coating has likely failed.

What is the correct method to control speed when descending a long slope?

When descending a long slope, the correct methods to control speed are: 1. For manual transmission vehicles, shift the gearbox to a lower gear to utilize engine braking, while also applying the brakes to maintain a reasonable speed range; 2. For automatic transmission or semi-automatic vehicles, switch the gearbox to manual mode and select a lower gear, or shift to L (Low) gear if available, using the gearbox braking in combination with the brakes to control speed. When descending, the gear selection should be based on the slope gradient—the steeper the slope, the lower the gear should be. Essentially, the lower gear helps to restrain the vehicle's speed from becoming too high, avoiding prolonged use of brakes which could lead to brake component damage.
